The Revel Ultra Ti single-exit titanium catback is a model-specific exhaust option listed for various Subaru WRX and STi years (2008–2021 across supported chassis). Built as a single-exit catback in titanium, it replaces the factory exhaust routing with a titanium-finish system intended to provide a durable, corrosion-resistant alternative and an updated single-exit appearance for the supported WRX/STi applications.
